             Summary: WSDL20ToAxisServiceBuilder.java:1235 & 1255 (XML External 
Entity Injection)
                 Key: AXIS2-5879
                 URL: https://issues.apache.org/jira/browse/AXIS2-5879
             Project: Axis2
          Issue Type: Bug
          Components: jaxws
    Affects Versions: 1.7.6
            Reporter: Donald Kwakkel
            Priority: Critical


XML parser configured in WSDL20ToAxisServiceBuilder.java:1235 and 1255 does not 
prevent nor limit external entities resolution. This can expose the parser to 
an XML External Entities attack.

Proposed solution: Always disable external entities:
{code:java}
        public static DocumentBuilderFactory createDocumentBuilderFactory() {
                DocumentBuilderFactory factory = 
DocumentBuilderFactory.newInstance();
                factory.setNamespaceAware(true);
                        try {
                                
factory.setFeature("http://xml.org/sax/features/external-general-entities";, 
false);
                                
factory.setFeature("http://xml.org/sax/features/external-parameter-entities";, 
false);
                        }
                        catch (ParserConfigurationException e) {
                                throw new IllegalStateException(e);
                        }
                return factory;
        }
{code}
